this is the most elaborating way of programming that invokes all the materials that you study in c programming. Thank you

[AZureSC]

Thank you for providing this information for free man, appreciate it! I am about to go into my second year as a CS major and did not know where to go after learning Java so these tutorials have been great for learning the basic syntax of another language

[muhammadshahzaib]

Watching this tutorial in 2024 and absolutely enjoying learning C from you. Followed your course from the first video till the last and now i feel very confident in C language.
This guy never disappoints🙌.
Respect man❤❤
Keep making such insightful and useful videos

[beckbrook]

From a student who's learning programming and runs out of time, thank you a lot Bro Code

[partykeeps]

I'm just beginning to learn and followed this example. It's great, thank you. So far I've added the ability to choose whether to be X or O, who goes first, and made it alternate who goes first after each game. I'm going to work on the AI now.

[solozlegend]

Yo! Very good informative video . Btw advance congrats for 200k . U deserve more

[takashikumi]

I love you bro keep it up I am learning a lot thanks to you!! <3

[OfficialSumanMahato]

Thanks bro, nice approach for this problem
This video definitely deserves more views

[AbhitejBokka]

Yo Bro Code, u gotta hit us up with some videos on pointers. I appreciate all the hard work u put in here cuz it really translates to a learning experience for me and many others here.

[Palmieres]

Thank you for this. I easily altered it to make it a two player game, add an option for player names and a nice little menu. In the words of Homer SImpson "GAAHHHHGGHHH! More, please!"

[sabaabiri]

hi bro I have ended this tutorial right now, and I want to start c++ tutorial . I want to say thank u for teaching fast and very good . best regards

[official-k.i.d.u-k]

"Sit back relax and enjoy the show" :) and i also finished the course, Thanks bruh

[astudent]

Completed the whole series and now I'm ready to ace my midterms

[minecraftcookie]

Thanks ! I modified the code to set pawn and a toss will be performed to decide who will go first

[Rid-E]

Correct me if I'm wrong. The checkFreespaces() function within the computerMove() function is unnecessary since the main function already contains a while loop checking for that. The printWinner(' '); statement in the computerMove() function is also pointless since the winner=checkWinner() is already doing the job in main function.

[bsykesbeats]

Thank you, awesome breakdown....One small improvement: if you add && board[i][0] != ' ' to the check rows if statement in the checkeWinner() function (and of course && board[0][j] != ' ' for columns etc) it will ensure that it doesn't prematurely return from that function if it sees that for instance the top row is still all ' ' even if you win in the bottom row. It doesn't come up that often, but it's irritating when it does, I made a 2 player version of this so I was able to force this corner case and it drove me crazy until I finally figured out how to solve it with he simple fix above.

[MandipChhetri]

My first game reloaded thank you❣️ love from 🇳🇵

[MehediHasanu]

Hey bro..first of all thanks a lot for all the free courses... I would like to know something, How can i prevent the player from winning? And How the computer can block the player winning move?
like, if player move 2 X horizontally or vertically, how the computer can prevent player from winning? you response would be very helpful... I'm eagerly waiting for your response.

[gitch]

now we just need a video on this but with the language C# :)
